Abstract (en)
[origin: EP0084873A2] A planar heater for a liquid crystal element comprises a thin metal plate having a relatively high specific resistance such as stainless, nichrome, nickelchrome iron alloy, etc. The thin metal plate is subjected to etching-working to form a mesh-like heat generating body, opposite ends of which are provided with terminal portions.
